Beisiier, Les Aussies, cane Applicationctoher 1, 19411, fil erial No. 413,502 seams. (01. 83-53) This invention relates to a device for. crushlng'and .pulverizing' rock and ston as well as ores. The device in general comprises a wedge shaped chamber or ,hopper whichreceives the rock to be crushed. The hopper has atleast one of its walls pivoted and adapted to receive a short rocking-like motion from a power supply rne'ans. In the hopper, the rock i broken or chewed by the rocking wall, and then fed through .a throat to another chamber, usually much smaller than the first, where the rocke -1rd stone is further reduced in size or pulverized by a. reciprocatory tongue that works between a pair of grinding elements. From the pulverizer, the finely divided rock or stone is dropped into a receptacle to be carried away. a An object ,of this invention is to present a sturdy and simple device forbreaking and pulverizing rock, stone and ore; the device being economical of manufacture and suitable for construetion in small sizes as well a large sizes.

Another object is to provide a rugged device that first breaks or chews the rock to a predetermined size and then vf rictiomally further reduces the sizevof theyrock toa very fine-mesi a 1 I Other objects, advantages and features; my invention will ap ear frcmlth r wmpanw drawings, :the; subjoined detaileddescription; the preamble of thesespecificationsand; the appendi aim .ii .1. ipplicant lis a t Q l us ate anddeseribe one pf the; forms of his invention in erder to teach one howte make; use and vehdtlie samj, but it is to he understood.- that; the drawin s a ld description thereof are not tolimit the inverrtion in any sense whatsoever, except as limited by the appended claims; V I ahe r w s:- v ,7

Between the set of -slabs k3 and-B6,, there is provided-a hopper-42' and a threat, and: hetwieen 'the set of slabs M and 3l',-there= is provided a hopper 44 and a throat at: securely fixed to' theslah I3 is a hardened steer gririamaveneer plate 46 anti-"a'sifnilarveiieer platetris fixed to the slap m.

At the bottom of the slabs there are recesses into which snugly fit the removable hardened steel grinding rolls 52, 53, 54 and 55, each of which are held against rotation by their respective set screws 56. Between the grinding rolls are elongated hardened steel plates 51 and 58, as shown, these plates being fixed to their respective support rods 59 and 60. The ends of the rods are pivoted to the side levers 6| and 62,

the ends of which are pivoted to the bottom of walls I and 2 at 63 and 64 respectively, The free end of lever BI is pivoted to the vertical push and pull rod 55 and the free end of the lever 62 is pivoted to the vertical push and pullrod 66. A shaft 61 joins with the tops of the push and pull rods, the rods 65 and 66 being journalled to a bore in the rocker arm 2| at 68.

To adjust the pressure of the grinding rolls against their respective plates 51 and 58, the screws 69 and 70 are employed. Cross bars ll and 12 have their ends fixed to the side walls I and 2 and each of which have threaded central bores to receive their respective screws.

The faces of the grinding plates 46, 41, 48 and 49 have a plurality of cross elongated teeth 13 which engage the rock or stone to be crushed. The arcuate motion of the slabs l3 and I4, squeeze and grind the rock or stone in the hoppers 42 and 43 until the rock is broken to a small enough mesh to pass into the throats 43 and 45. From the throats, the crush rock is forced between the plates 51 and 58 and their respective grinding rolls where the rock is pulverized; the degree of pulverization depending upon the setting of the screws 69 and W. The pulverized rock then falls from the device into any suitable receptacle or carrier, not shown, which is placed under the supporting beams ll and I2. When a portion of the grinding rolls 52-55 become worn, the set screws 56 are loosened and the rolls rotated in their respective recesses to bring a new grinding surface into use.
